The other end of the Sunbury sub is at Sunbury, PA where it connects in with the NS Buffalo-Harrisburg line. Im not sure of the exact mileage but it somewhere around 140 miles end to end. There are 3 controlled sidings between Binghamton and Scranton at Hallstead PA, Hop Bottom, PA and LaPlume/Dalton PA. I think there are 3 or 4 more between Scranton and Sunbury. Train counts vary but about 5-6 a day south of Scranton/Wilkes-Barre and 10-12 a day north of Scranton (About half of the traffic splits off at DuPont/Wilkes-Barre and uses the R&N/NS tracks to the Allentown area). Thats the basics, someone else can fill in the details.
